Hi, how well does this work with Focal Clear headphones (55 Ohm) in Unbalanced 6.5mm and Balanced 4 pin XLR. Does the DX7s 10/20 Ohm output impedance from the amplifier affect the sound quality of low impedance headphones?

投稿日: 18/02/08 14:46

Dear J,Topping hadn't test the headsets, DX7s output resistance 10/20 uefa will slightly affect the frequency response of earphone.Thank you.

Dear Sir,  I order the TOPPING DX7S USB DAC around March,2018. It function properly until few days ago it's no audio output from RCA L ch and R ch but It's still have audio output from the 6.3 mm plug. Please advise what should I do to get the audio out put from RCA out.    Thank you in advance.    Best Regards    Kamchai

Hi Kamchai,  Please switch to DAC+HP mode. If it is HP mode, the headphone jack has audio output, but RCA L ch and R ch have no sound. Thank you!
